Disconnects the connection to an Open Protocol device.

Returns:

    Disconnect
    A variable of the OpcMethodReturnValueVoid type. The method has no command-specific return values.

Examples:

In addition to the parameters already explained, the following variables must be created / transferred for the implementation in TwinCAT 3:

Beckhoff parameter:

    bOpenProtocolDisconnect
    A boolean variable that can be used to trigger the execution of the disconnect command.
    OutputDataOpenProtocolDisconnect
    An instance of the "ST_VoidOutputData" structure into which the return value of the Disconnect method is written.
    hrOpenProtocolDisconnect
    This can be used to monitor the execution of the command. Error codes have the type "HRESULT".
    fbOpenProtocol
    An instance of the "FB_OpenProtocol" function block supplied with the DEPRAG Smart library.
    sDeviceId
    A DINT value that identifies the device in the list of devices registered with the DEPRAG Smart OPC UA Server.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client. 


VAR
 bOpenProtocolDisconnect    : BOOL;
 OutputDataOpenProtocolDisconnect : ST_VoidOutputData;
 hrOpenProtocolDisconnect   : HRESULT;

       fbOpenProtocol   : FB_OpenProtocol;
END_VAR

hrOpenProtocolDisconnect := fbOpenProtocol.Disconnect(
            bExecute    := bOpenProtocolDisconnect,
            ConnectionHandle := depragSmartConnection.ConnectionHandle,
            sDeviceId   := '0',
            OutputData   => OutputDataOpenProtocolDisconnect);
IF hrOpenProtocolDisconnect <> S_FALSE THEN 
 bOpenProtocolDisconnect := FALSE;
END_IF
